This is why I suggested using the GW link line to run some of the
Crossrail trains to Greenford; unfortunately, the Central Line viaducts
would make it very difficult to get a link in from the bay platform to
the link line.

Would Greenford alone justify the expenditure on continuing up the old GW
Birmingham route? If stations were added at Park Royal and Hangar Lane then
it might help the figures along and you might as well reinstate a main line
platform at Greenford, rather than remodelling to use the existing LU
platforms, which would probably cost just as much to do (if not more). In
that case, you could argue that you might as well continue to South Ruislip
or West Ruislip, to provide a useful transport interchange with the Chiltern
line, in which case you might as well continue to High Wycombe - then you're
virtually back in the position that was originally planned for Crossrail,
with a Wycombe branch!
